Accelerometer Controlled Pong

[youtube=http://www.youtube.com/watch?v=jYVgXYtxk4E]

[Perry’s] awesome AcceLED Pong project gives new life to a classic game by adding acceleration-based control. The pong paddles are moved by tilting the circuit left or right. Motion is measured by an ADXL203 dual axis accelerometer, and an ATMEGA32 microcontroller converts acceleration into ball and paddle movement. The game display is a three-color SparkFun 8×8 LED matrix with serial interface.

[Perry] also used a similar setup to make a USB LED spectrum analyzer fed by the Linux XMMS media player.

Punch Your Alarm Clock


This is probably the most entertaining “application note” I’ve ever seen. These things are usually a bit dry, ok, they make your eyes turn to a previously unknown state of matter. This one involves making your alarm clock snooze when you beat it. The trick? Wire an accelerometer to the snooze button. It takes a bit of supporting circuitry, but looks do-able for anyone worth of their soldering iron. Thanks to [Andy] for sending it in.

Wiimote Car Accelerometer


This one’s pretty simple, but anyone who’s ever spent time tweaking an engine will appreciate it. [Kevin]’s been using a wiimote to measure the acceleration of his car. He put together a script to dump the accelerometer output to a CSV file, then graphed it with Excel. He notes that the accelerometer output isn’t that precise, but it’s good enough to give you feedback on your mods.
